Applying the finite element method, the function of finite element analysis software AnsysWorkbench is powerful. Analysis 30 groups of different groove curvature radius coefficient model in extreme condition, obtained in applying extreme working conditions, stress and deformation data. Analysis results show that the inner groove curvature coefficient is 0.525, the outer ring raceway curvature coefficient of bearing is 0.52 when the slewing bearing shows maximum carrying capacity. Calculation, results provide analysis basis for slewing bearing design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
